System Board 1-1
1.1 Features
The M19A is a dual-processor system board built on an ATX
baseboard utilizing two Intel PentiumII processors running at
333/66, 350/100, 400/100, or 450/100 MHz. It is integrated with the
Intel 440BX system controller, which consists of the PCI/AGP
controller and the PCI/ISA IDE accelerator (PIIX4).
The PCI/AGP controller host bus interface supports a Pentium II
processor with 66 or 100 MHz bus frequency. It also provides a 72-bit
DRAM that supports synchronous DRAM (SDRAM) DIMMs. The
PCI/AGP controller introduces a new technology, which is the
Accelerated Graphics Port (AGP) interface. Supporting up to 133 MHz
data transfer rate, the AGP interface boosts graphics performance.
The PIIX4 is a multifunctional PCI device controller implementing
system functions including PCI IDE, universal serial bus (USB)
host/hub, and enhanced power management. It also supports Ultra
DMA/33 synchronous DMA-compatible devices.
The four DIMM sockets on board allow memory upgrade to a
maximum of 512 MB and supports 72-bit DRAM using synchronous
DRAM (SDRAM) DIMMs.

1-2 User’s Guide
A 50-pin Fast SCSI (Small Computer System Interface) and a 68-pin
Wide SCSI comes with the system board to connect SCSI devices.
Wide SCSI supports 32-bit transfers while fast SCSI uses a 16-bit bus
that doubles the clock rate to support data rates of 40 Mb/s.
The M19A system board also supports the USB (Universal Serial Bus)
connector, and other standard features such as two UART NS16C550
serial ports, one enhanced parallel port with Enhanced Parallel Port
(EPP)/Extended Capabilities Port (ECP) feature, a diskette drive
interface, and two embedded hard disk interfaces. The board also
includes a built-in 10/100 Mb/s Intel 82558 LAN chip that supports
Wake-On-LAN (WOL).
The system supports the power-management function that conforms
to the power-saving standards of the U.S. Environmental Protection
Agency (EPA) Energy Star program. It also offers the Plug-and-Play
feature. This feature saves the user from configuration troubles, thus
making the system more user-friendly. The system board supports two
optional features, ASM Pro and Remote Diagnostic
Management (RDM), that allow better server management. The ASM
Pro detects problems in CPU thermal condition, CPU working voltage
detection (±12V/±5V/3.3V/1.5V), and PCI bus utilization calculation. It
also detects if the CPU fan or the chassis fan malfunctions. RDM
allows execution of the RDM diagnostic program from a remote RDM
station to fix detected problems or to reboot the system.
The system is fully compatible with MS-DOS V6.X, DOS/V, IBM OS/2
Warp, Novell Netware, Novel SFT III, SCO UNIX, Windows NT and
Windows 95 operating systems.

1.5 ESD Precautions
Always observe the following electrostatic discharge (ESD)
precautions before installing a system component:
1. Do not remove a component from its antistatic packaging until
you are ready to install it.
2. Wear a wrist grounding strap before handling electronic
components. Wrist grounding straps are available at most
electronic component stores.
Do not attempt the procedures described in
the following sections unless you are a
qualified technician.

1.6 Installing the Pentium II processor
The following section will briefly explain and illustrate how to install the
Pentium II processor.
You have to attached the heat sink and fan
before installing the Pentium II processor into
the system board.
1.6.1 Attaching the Processor Heat Sink and Fan
The Pentium II processor module comes with holes on one side to
hold the clips of the heat sink and fan. The upper set of holes (near
the latches) on the processor are wider and should match the wider
ends of the clips on the heat sink. The lower set of holes are smaller
and should match the narrow ends of the heat sink clips.
Figure 1-3 Matching the Fan-Heat Sink Clips with the Holes on
the Processor
Wide Holes
Narrow Holes
Wide Clip Ends

System Board 1-11
Follow these steps when installing the heat sink and fan into the
Pentium II processor module:
1. Remove the thermal tape protector at the back of the heat sink.
2. Insert the wide clip ends into the wide holes on the processor and
the narrow clip ends into the narrow holes.
Figure 1-4 Inserting the Clip Ends into the Processor Holes
3. Use a screwdriver to press and lock in the wide end of a clip first.
Then without lifting the screwdriver, point it downward to press
and lock the narrow end of the clip. See Figures 5 and 6 for the
illustration of this step.

1.6.2 Installing a Pentium II Processor
Follow these steps to install the Pentium II processor to the socket on
the CPU board.
1. Place the retention mechanism over the processor socket on the
CPU board. Secure it with the screws that came with the
package.
Figure 1-7 Installing the processor’s Retention Mechanism
2. With the processor module golden fingers pointing downward,
align the processor to the posts of the retention mechanism then
lower it down. See Figure 1-8.
The golden fingers of the Pentium II module
are slotted such that it only fits in one
direction. Make sure that the module groove
matches the one on the processor socket.

1-14 User’s Guide
3. Press down the processor module until the golden fingers
completely fit into the socket.
Figure 1-8 Installing a Pentium II Processor
4. Press the latches on the sides to lock the processor module into
place.

1.6.3 Removing a Pentium II Processor
Follow these steps to remove the Pentium II CPU module from the
slot.
1. Unlock the latches that secure the processor module.
Figure 1-10 Unlocking the Module Latches
2. Firmly hold the processor module and pull it out of the socket.

1.7 Installing the Termination Board
When you use only one slot on the CPU board, you must install a
termination board into the empty slot.
Follow these steps to install the termination board:
1. Position the termination board over the empty slot.
2. Carefully insert the golden fingers of the termination board into
the slot until the board fits completely.
Figure 1-12 Installing the Termination Board
Do not forget to install the termination board if
you only have one processor.

System Board 1-17
1.8 Memory Upgrade
The four 168-pin sockets onboard support SDRAM-type DIMMs. You
may install 32-MB, 64-MB, or 128-MB DIMMs for a maximum of
512-MB system memory.
The SDRAM DIMMs should work under 3.3 volts; 5 volt memory
devices are not supported. Memory module with a timing setting of 66
MHz are defined under unbuffered DIMM specifications, while 100
MHz modules are defined under Intel PC-100 SDRAM specifications
and PC registered DIMM specifications.
Do not use both 66 MHz (unbuffered) and
100 MHz (registered) SDRAM together. This
might cause your system to malfunction.
Each of the sockets represents one independent bank. This allows
you to install DIMMs with different capacities to form a configuration.
1.8.1 Memory Configurations
Table 1-3 lists some system memory configurations. You may
combine DIMMs with various capacities to form other combinations.

1.8.2 Installing a DIMM
To install a DIMM, align it with the socket and press it down until the
holding clips secure the DIMM in place.
The DIMM socket is slotted to ensure proper
installation. If you slip in a DIMM but it does
not completely fit, you may have inserted it
the wrong way. Reverse the orientation of
the DIMM.
Figure 1-13 Installing a DIMM

System Board 1-19
1.8.3 Removing a DIMM
To remove a DIMM, press the holding clips on both sides of the socket
outward to release the DIMM.
Place your forefingers on the top of the DIMM
before you press the holding clips to gently
disengage the DIMM from the socket.
Figure 1-14 Removing a DIMM
1.8.4 Reconfiguring the System
Reconfigure the system after installing or removing DIMMs.
Follow these steps to reconfigure the system:
1. Reboot the system. A memory error message appears, indicating
that the total memory does not match the value stored in CMOS.
2. Press + + .
3. Press twice to exit Setup and reboot the system. The system
boots with the new memory configuration.

1.9.1 Installing PCI Cards
To install PCI cards:
1. Locate the PCI slots on the system board.
2. Remove the bracket on the housing opposite an empty PCI slot.
3. Insert a PCI card into the slot. Make sure that the card is properly
seated.
4. Secure the card to the housing with a screw.
When you turn on the system, BIOS automatically detects and assigns
resources to the PCI devices.
